METAL STRAP FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 403,245, dated May 14, 1889.

Application filed October 22, 1888. Serial No. 288,788. (No model.)

To all whom t may concern:

Be it known that I, SPENCER C. CARY, a citizen of the United States, residing at Baldwin, county of Queens, State of New York, have invented certain new and useful Improvements in Metal Straps for Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication.

My invention consists in a box-strap composed of metal bands or strips united longitudinally in succession endwise by means of the particular devices hereinafter described, and as recited in the claims, and in a boxstrap of metal having a roughened surface along its central line and extending longitudinally of the strap, as hereinafter described.

In the drawings, Figure l is a plan or top face view of a metal box-strap containing my invention. Fig. 2 is a plan, enlarged, of the ends of two sections of my box-strap and showing the means I employ to joint said ends together. Fig. 3 is a vertical section of the same on the line c Fig. 3. Fig. 4 is a plan, enlarged, of a portion of my box-strap and showing the roughened central portion on its face extending longitudinally of the band.

In carrying out my invention I take strips or bands of metal of the desired width and thickness, and I joint these sections A of my strap together by forming at or near the end of each section an oblong corrugation, which extends laterally of the band between its edges, as shown at a, and it will be found desirable to form two of said lateral corrugations, as shown in the drawings, parallel to each other at the section end and with a surface or web, a', of the strap between them. When the section ends are imposed upon each other tlatwise, as shown in Figs. 2 and 3, the corrugations on the under section will iit into the recesses formed on the under face of the upper section by the corrugations therein. An opening or hole, a2, is then punched in the lapped sections in the web between the corrugations, and a rivet or eyelet, d3, is inserted therein and clamped down tightly upon the section-surfaces. In the 5o joint thus constituted the eyelet or rivet will bind the sections together, while the engaged corrugations will prevent lateral movement of the sections upon eachother, therebymaintaining the entire strap in a continuous rec- 5 5 tilinear state throughout its length.

At B is shown a roughened portion 0f the face of the box-strap. This roughened portions extends centrally of the face of the strap and throughout the length thereof. Box- 6c straps of at metalbands as heretofore made have been smooth surfacially, and in driving the nail through the strap, which serves to fasten the strap to the box, the point of the nail is liable to slip or glance upon the surface of the strap, causing annoyance and loss of time. By means of the roughened portion B on the face of the strap, as described, a surface is formed upon which the nail-points will hold firmly when the nail is to be driven, 7o

and upon which, as such roughened part B extends longitudinally of the strap, the nails may be placed indiscriminately when fastening the strap to a box.

I do not intend to claim herein, broadly, a

joint composed of corrugations in the lapped section ends fitting into each other and an eyelet or rivet passed through said lapped ends, but to limit the claim thereto herein to the specific means shown-namely, the oblong 8o corrugations a in the ends of the sections and extending laterally thereof between the edges and fitting into each other when the section ends are lapped, as described, together with the eyelet or rivet a3, passing through and 9 .1. A box-strap consisting of a metal band of indefinite length, composed of strips or sections of similar width having at their ends the oblong corrugations a, extending latererally of the sections between the side edges thereof, said sections being lapped upon each other endwise successively, with the said corrugations thereon fitted into each other .at the laps, and an eyelet or rivet, a3, passed through and extending,` lon gitudnally of the strap the the lapped ends alongside said corrugations roughened surface B, substantially as and and clamped down upon the faces of the bandfor the purpose set forth.

sections, substantially as and for the purpose SPENCER C. CARY. 5 set forth. lVtnesses:
